Apii-lic'ation filed August 10, 1926. 'Seria 1 1\T0.'-128,498.

' 'Ihi-s invention relates to mechanism for removing scale and .other iorelgn matter from metal plates as thelatter enter the rollsof a-rolling mill and the principal ob- 'jectofthe'inventionis to provide a simple scraper mechanism 'mounted upon theflroll' housings at the entrance side of the ;mill whereby adherentioreign matter is effectively removed fronrthe metal plates.-

Another object of the invention is the provision oi aunitary scraping mechanism comprising a supporting plate, ascraper member, guidesfor the-scraper member,-and means for actuating the scraper member all mounted on the supporting plate, the latter being-secured to the roll housings in adjusted relation to the entrance passage.

A further'object :of the invention is the provision of guides 1501 the scraper member,

these guides being laterally-movable -With relationto the inlet opening of the'housing so as not to interfere With the work as i the latter enter into the'rolls. 1

Other objects and purposes will become apparent'asthedescription of-the invention proceeds. For a complete understanding of the invention, reference is -tobe had to the accompanying P drawings forming of this specification.

A supporting :plate 11 having inwardly bolts '18, scraper bar or blade 17.

upper end of sa-idscraper plate 16has at-g scraping mechanism mounted detail sectional viewshowing the slotted link connection between theextending side pieces 12 suitably spaced from the ends thereof is attached to the roller housing R lby means of angle brackets 13, as is clearly shown 'in Fig. 3. The supportingrplate 11 has outwardly extendmg vertical ribs 14 forming side guides for a scraper plate '16, which has removably mounted'on it lower end, as by means of The tachedithereto a longitudinally slotted link 19 which has connection with an actuating lever 20 that'is pivoted upon the plate 11 at 21. It willhere'be noted'that the scraper plate 16 :is movable with relation to "the lever 20 by reasonof-the Slotted link con nection .justfdescribed, and it will also be noted that the link 19 is pivotally secured to the scraper plate '16 at 22 to permit the;

required relative movements of the actuat ing lev'er 20-and scraperplate. The connection betweenthedink 19 and 'thelever 20is shown-in detail-in Fig 6, and itwill there be seen that a headed bolt- 23 carried by said lever '20 has a reduced threaded exy tension 23 passing through the slot'26 in the link "19,=and that a nut 27 secures th parts against displacement.

TLocated in front of 'the upper part of i the Scrapper plate 16' is a horizontally 'disposed {ban-28 secured'at its'ends to the plate I 11, as bybolts 29. Saidbarlhas init's rear face recesses 30 1 in which are received vertically movable guides' -31 and 31 which in their :normal position have'their lower end. portions occupying a level below the path of travel of sheets 'to the rollsoi the mill, and' the ilower inner'sides of which are'provided with removable wear plates '32 and 32?, respective aly. The j upper end of the guide-31 is" slotted, as at 33, and is connected to the' lever F 20 through the intermediacy'of-a slotted link 35, the latter being rigidly attached T to the lever 20 by means of bolts 36. A pivot bolt 34 attaches said guide 31* to said link 35, beingdirected through'the slot 33 anda horizontal slot '35 provided'in aacrosshead portion of said link. Said slotted link connection permits the guide '31 to move laterally and vertically for a purpose which willhereinaiter'be described. The guide 31 has a slotted upper" end 37 connected by a'bolt 38"to one end of a longitudinally slotted lever '39 which-is pivoted to the plate l l-at lO'and which has 1 its opposite end connected, as at -12, to an end of a link 41 which has its opposlte end connected by a bolt a3 to a horizontally slotted link 44 secured to the lever 20. The

tion of said guides when said lever is moved 111 a; COlHltQlFClOCkWlSB dlrectlon aboutv its pivot. 21 and for lowering said guides upon clockwise movement, as when the sole noid 46 is energized.

It is advantageous to provide for the movement of the guides 81 and 31 outwardly relative to the path of travel of sheets entering the mill so that no interference is offered by the guides to the plate asthe forward end of the latter passes between said guides. To this end the guides 31 and 31* are arrangedto be moved laterally during their upward movement. As shown by Fig. 5, the guides 31 and 31 may move laterally in the recesses 30. Their. upper ends may move laterally by reason ofthe slotted link connection hereinbefore described. To permit lateral movement of. their/lower ends the guides 31 and 31 have their outerredges inclined, as shown at 4:7 and- 4E8, respectively. Rollers 49 mounted in slotted hold-,

ers 50 serve as anti-friction abutments for the outer edges of said guides 31' and .31. Said holders are secured to the plate 11 by bolts 51, as shown in Fig. 2,.the slots thereof providing for adjustment. The guides .31 and 81 are provided With attached vertical rods 52 and 53, respectively, and on. these rods are adapted to riderollers 54 and 55 which are yieldablyheld there; againstby springs 56 secured to eye bolts 57,

' the latter being mounted in the plate 11..

Pivoted rods 58cand 59 suspendtherollers 54 and 55 from the cross strip28. .It will thus be seen that as the lever QO is moved in a counter-eloclnvise direction about the pivot21 tomove the scraperplate16 up-. wardly, the guides 31 and 31 are likewise moved upward and, at thesame time,"are

' actuated to move laterally outward in oppositedirections because of the tapered por and 48, the springs 56 causing the upper parts of the guides 31 and 31 to follow the lateralmovement of parts {L7 and 4-8 thereof.

From the foregoingdescription the con struction, operation and advantages of the novel mechanism will be readily understood. As the forward end of the plate P approaches the rolls of the roll housing, the

. scraper mechanism and guides are withdrawn from the path of travel thereof.

Having passed by said elements, the latter are actuated through the lever 20 to'resume their normal positions, as shown Fig, 2,

the lower plate. 7
